Invalid bound statement (not found): com.heima.mapper.MyMapper.selectList
时间: 2023-10-28 17:54:04 浏览: 38
As an AI language model, I cannot determine the specific issue without seeing the code and the context. However, the error message suggests that the bound statement "com.heima.mapper.MyMapper.selectList" could not be found. This could be due to a typo in the statement or the file path, or the statement might not exist in the MyMapper class. You should check the code to ensure that the statement is properly defined and spelled correctly.

解释下Invalid bound statement (not found): com.heima.mapper.MyMapper.selectList
这个错误通常是因为 MyBatis 找不到指定的 SQL 语句。可能的原因包括:
1. SQL 语句的 ID 拼写错误或不存在。
2. mapper 文件中没有定义该 SQL 语句。
3. mapper 文件中定义的 SQL 语句没有被正确映射到 Java 接口方法上。
4. mapper 文件中定义的 SQL 语句没有使用正确的语法。
为了解决这个问题,可以按照以下步骤进行操作:
1. 检查 SQL 语句的 ID 是否拼写正确,是否存在于对应的 mapper 文件中。
2. 确认 mapper 文件中定义的 SQL 语句是否正确映射到了 Java 接口方法上,并且方法名和 SQL 语句 ID 一致。
3. 检查 SQL 语句是否使用了正确的语法,例如是否缺少必要的参数或语句中含有语法错误。
4. 如果以上步骤都无法解决问题,可以尝试重新编译项目或重启应用程序。

Invalid bound statement (not found): com.cvg.electric.mapper是一个数据库查询异常。这个异常意味着在执行数据库查询时找不到指定的SQL语句。根据引用和引用的内容,可能是因为在使用mybatis或mybatisplus时未正确配置或使用Mapper接口导致的。解决这个问题的方法是通过检查Mapper接口的配置,确保正确继承BaseMapper,并且对应的SQL语句在XML文件中正确定义和映射。具体的解决方案可以参考引用中给出的示例代码。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
